Lo esencial

Cornices remain the primary concern. Solar radiation is a common cornice trigger. Limit your exposure when it's cloudy and completely avoid cornices when it's sunny.

Snowpack Summary

5-10 cm of new snow on Saturday with light southerly winds may have created small wind slabs on lee features below alpine ridgetops. The new snow will likely be sitting on hard surfaces created by strong winds earlier in the week. Elevations below roughly 1300 m are experiencing a daily melt-freeze cycle and the snowpack is likely isothermal. The February crust and facet layer is 70-90 cm deep in the Houston Telkwas sled area and a deep persistent faceted weak layer is still lingering near the bottom of the snowpack in all areas.
